[QUOTE="Heide264, post: 6839756, member: 610716"] Been having a small electrical battle with a system in my 97 astro van I moved over from an older car. I know there are a lotta resources around, and I've done some reading, but I wanted to get some opinions on the matter before I start ripping more of it apart, don't have too much free time anymore to mess with it sadly. Everything sounds great, except for an annoying crackle/popping sound, mainly when I back off the pedal after the rpms are a bit high on the car. It doesn't get worse with volume - always at the same level as the music. I just re-grounded the amps to the car body behind the driver seat - I can take pictures if anybody thinks this is the issue. Didn't get much better or worse after redoing the ground from the seat bolt itself. I have 2 suspicions: 1.) My grounds from my 2 amps first go into a distribution block, then into the floor ground. The 2 wires going into the dist block and the one coming out are all the same size as my power wire. Not too hard to fix, but I honestly don't think this is the issue personally, but looking for opinions 2.) I saw several posts about the rca ground fuse blowing in the HU. I have an old eclipse HU, and I have changed power connections a couple times while the RCAs were connected at one time or another probably. I could try doing the wire wrap routine around the jacks and grounding it, but it seemed that was mostly for pioneer units. I'd like to swap it for a newer pioneer unit I have (much better radio reception), but it only has one set of preouts. My sub enclosure has a passive filter, so I was debating just using a splitter and splitting the preouts... not sure if that is a terrible idea though. Thanks, Let me know if any more information would help. Tried to keep the post reasonably short. [/QUOTE]
